Weekend contest #17: Let us show you off!

For our booth at MakerFaire, we 3D printed our back wall. If you ignore Ben, Savannah, and R2D2 you can see them hanging in the background

For SIGGRAPH, and every show going forward, we would love our booth to have EVERY material represented on the wall, and each panel to be designed by our community.

So that's where you come in.

We are looking specifically for panels designed for Alumide and Elasto but are open to other materials like FUD and Steel too (we have enough WSF though!)

The restrictions are:
Size: 30cm x 30cm x the materials required thickness - (12" high x 12" wide) so about one foot square.
Holes: four holes, one in each corner minimum diameter 10mm - these are so we can connect them together as show in the picture
Complies with all material guidelines
Deadline is uploaded by Tuesday July 2nd.

Each Material will have it's own winner, and there can be multiple winners so multiple prizes of $25 Shapeways bucks are up for grabs!

Here is my submission! A panel of reptiles that would be great in elasto, the thin wire lizards would expand and allow you to bend the thing all over. I made the wires a bit over 2mm so it should stand the weight.

Am I reading the size requirements right? They seem to specify a 300 x 300 mm square, but Alumide has a max bounding box of 230x180x310mm according to the design specifications. Can the square be smaller than 300 mm, and if so, how small?

The size above of one square foot is not quite right. Michael did say "Complies with all Material Guidelines", which would include limiting the model to the max build volume available for the various printers.

For example, FUD needs to be limited (for this contest) to around 120x120mm
For Alumide, I'd stick to 220x220mm or so

Unless of course, if you were design your object at 150x150mm and expect to connect 4 of them together to make up the 300x300mm size.

Patience, Persistence, Politeness - the 3Ps will help us get us to Perfect Printed Products.

I made a panel based on a bracelet I designed. The panel exist of two lines and 27x27 little hearts with rings on them to connect to each other.
It is 300x292 mm, with wires of 1 mm. It's designed for elasto, so you could really stretch it.
My laptop didn't liked it all. The stl file is over 500 mb, and I saved it in the lowest setting.

I've designed woven panels at 150 mm for Alumide and at 300 mm for Elasto Plastic. Although the 150 mm panel could be printed in a variety of materials and hung together to form the full size panel. It was difficult keeping it under 1 million facets.

I have two designs. I call the first one the maze. You could look at it from either side but looking at the convex side first makes you wonder what's on the other side. Why is there a segment that is out of place? You are compelled to look at the other side!

My other design is based on a vent vane I designed to fix cracked ones on a house but at $26 it was still too expensive. (Speaking of which you guys could use a cheaper industrial quality WSF process that can have slight defects or gross colors if you recycle old dirty powders.) This panel has little handles on the three vent vanes so people can look inside. If you want a really neat panel get a standard 12VDC 120mm computer muffin fan and screw it on the back (you need to drill your own holes for your fan), Then hook it up to a switch or a periodic timer that cycles the power on and off from a battery or power supply to make the vanes open up in the breeze from the fan. There is an internal screen in the air flow path to protect little fingers from the fan if stuck in past the vanes. You need to put a screen on the back of the muffin fan if it is exposed. Instead of a fan the back side of the panel could be redesigned to connect to a vent hose but that would be another project. This thing is designed to be industrial trade show quality with 0.1 inch thick walls for the large panel parts. The vane peg holes are oversized about 0.38 mm around the pegs which may or may not allow this panel to be printed in one piece. I've never done that before. It might be a good idea to print the vanes separately from the main panel and then install them afterwards. Good luck if you print this beast!
